Socket通信，客户端和服务的互相收发------客户端接收代码块执行不了

[barrons]

public static void main(String[] args) throws Exception {
		
			
		
		ServerSocket ss = new ServerSocket(9052);
		System.out.println("开始等待某个连接");
	
		do{
		Socket s = ss.accept();
		System.out.println("获取到一个连接");
		
		DataInputStream in = new DataInputStream(s.getInputStream());  
		byte[] result =new byte[100000];
		
		int thislength = 0;
		int totallength= 0;
		do {
			thislength = in.read(result, totallength, 2000);
			
			if(thislength>0)
			{
				totallength +=thislength;
			}
			
		} while (thislength>0);
		
		byte[] response = new byte[totallength]; 
		
		System.arraycopy(result, 0, response, 0, totallength);
				
				String responseStr = new String(response);
				
				System.out.println("服务端接收:" + responseStr);
				
		String str="服务端发送"+responseStr;
		DataOutputStream out = new DataOutputStream(s.getOutputStream());
		out.write(str.getBytes());
		System.out.println(str);
		out.flush();
	
		}while(true);
		
		
//		ss.close();
	}

这是我测试用的服务端的代码 ，能收发

[barrons]

public static void main(String[] args) throws Exception {
		
		int i=0;

		while(i<10){
			Socket s = new Socket("127.0.0.1",9052);
			String str="客户端发送"+i;
		
			
		DataOutputStream out = new DataOutputStream(s.getOutputStream());
		 
		
			out.write(str.getBytes());
			System.out.println(str);
			out.flush();
			
			//到这里就执行不下去了
			DataInputStream in = new DataInputStream(s.getInputStream());
			byte[] result =new byte[100000];
			
			  int len;   

			
			int thislength = 0;
			int totallength= 0;
			do {
				thislength = in.read(result, totallength, 2000);
				
				if(thislength>0)
				{
					totallength +=thislength;
				}
				
			} while (in.available()>0);
			
			byte[] response = new byte[totallength]; 
			
			System.arraycopy(result, 0, response, 0, totallength);
					
					String responseStr = new String(response);
					
					System.out.println("服务端接收:" + responseStr);
							
					out.close();
					in.close();
				
		i++;
		
		
		 
		
		
	
		
		
	}}

如果把

			DataInputStream in = new DataInputStream(s.getInputStream());
			byte[] result =new byte[100000];
			
			  int len;   

			
			int thislength = 0;
			int totallength= 0;
			do {
				thislength = in.read(result, totallength, 2000);
				
				if(thislength>0)
				{
					totallength +=thislength;
				}
				
			} while (in.available()>0);
			
			byte[] response = new byte[totallength]; 
			
			System.arraycopy(result, 0, response, 0, totallength);
					
					String responseStr = new String(response);
					
					System.out.println("服务端接收:" + responseStr);
							
					out.close();
					in.close();
				

这一段注释掉就能执行了 但是不能接收啊 求大家帮忙解决……

这里的是我的测试用的客户端代码[/quote] 项目要求是要求 字节流 互相收发

[kainever]

我记得thinking in java 里说过 available （）得谨慎使用...... 还有 do while ... 不是不推荐用吗 DataInputStream是专门格式化读取的你怎么还用 read() 了......

[W-Aires]

System.out.println("服务端接收:" + responseStr);

服务端能执行到这句么，感觉很悬呢

[W-Aires]

thislength = in.read(result, totallength, 2000);

你调试下，应该阻塞在这，这种交互你需要一个简单的协议，另外data装饰类没太大意义

客户端10次循环,10个socket共用一个端口怎么可能

好久没用socket了想多了.上面完全错了
